Improving the optical properties of thin film plasmonic solar cells of InP absorber layer using nanowires
In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولOptical and Optoelectronic Properties of ZnS Nanostructured Thin Film
ZnS nanocrystalline thin films were grown into the polyvinyl alcohol matrix and were synthesized by chemical route. Films were prepared on glass substrate by varying the deposition parameters and pH of the solution. Nanocrystalline thin film prepared under optimum growth conditions shows band gap value 3.88 eV as observed from optical absorption data. The band gap is found to be higher (3.88 eV...
متن کاملOptical and Electrical Properties of Thin Film BaSnO3 Author
Thin films of the perovskite barium tin oxide (BaSnO3) were prepared and characterized by their structural optical, electrical, and photoluminescent characteristics. Film deposition methods included both RF sputtering and pulsed laser deposition techniques. High quality, oriented films having optical bandgaps ranging between 3.7 eV & 4.4 eV were produced on various substrates. The undoped films...
متن کاملAnisotropic Optical Properties of Thin-Film Thiacarbocyanine Dye Aggregates
Optical properties of thin films of aggregated thiacarbocyanine (TCC) dyes have been studied by means of spectroscopic ellipsometry and polarized IR spectroscopy. The experimental results reveal a strongly anisotropic response of the films, as quantified in the reported anisotropic dielectric functions over a wide range of frequencies. The studied TCC films exhibit both J-aggregate and H-aggreg...
